Sleep.

10 a week usually

On weekdays, I sleep around 4-5 hours bc I have trouble falling asleep early and am sleep deprived =/ On weekends, I sleep 9+ hours

6-7 hours on weekday, and may over 10 hours on weekend.

i used to sleep 4-6 hours per day in two cycles. now with pills i'm sleeping over 12 per day.

During work days roughly 3.5 - 4.5 (I get home at 8pm-ish, go to bed around 1-2am, get up anywhere from 5-5:30am and have to leave by 5:50am)
During days off... 10-12? Usually go to bed 3-4am and don't get up until around noon - 2pm.

4-6 T_T

I try to sleep 7-8 now 22pm-6am, but sometimes it's only 5/6

During the work week it's usually 4-6 hours a night. It's not enough. I just have so many things I want to do and already feel as if I don't have enough time in the day, if I slept longer i'd have even less time to do them. :)

6h is my optimal sleep time - if I sleep less - I'm sleepy for whole day, If I sleep longer - I'm tired for the whole day xD

10 hours sounds like too much, have you checked it out with your doctor? Could be some special condition.
I usually try to get 8 hours of sleep, but always fall short. Mainly due taking atleast hour to catch sleep after laying down. Sleeping is hard, and personally don't enjoy it. Although I usually remember my dreams.

I hate sleeping so I'd say around 6 hours but only because I have to. :/

4h and 6h max

Usually 5 or 6 hours, a couple hours more during the weekends.

Usually 6/7 hours per night.

5-6 hours on weekdays, 8-10 on weekends.

I would say 5-6 hours on weekdays and more much more on weekends ^^

0 because I am an insomniac. If by miracle I do get sleep, even 12 hours isn't enough to refill my energy. :/

Sleeping for 8 hours lately but that's because i'm unemployed at the moment so i can do that. While on a job it's more like 7. Never been mister sleepy panda boy but not getting at least 7 hours really shows on me.

Ah and i get like 6 on weekends because....well because fuck me i guess:D i just wake up for no reason.

I aim for 7-8 hours. I actually can't get more than that unless I'm really exhausted; I'll just be wide awake when I've had enough.
I can get by with 6-7, but then I won't be at maximum focus during the day. Less than that, and more severe side effects start showing up...

3 or 4 hours during week days, 5 on weekends

5-7 but i try to get at least 7 :C

usually 6-7 hours

2-4h, usually closer to 4 than 2, but the last 2 weeks I've slept closer to 2h than 4. 5h on weekends (2-3h the last two weeks).
